This paper examines trends in social class inequalities in young people's educational attainment and HE [Higher Education] entry between the mid-1980s and the end of the 1990s in England and Scotland. Using time-series data derived from the Scottish School Leavers Surveys and the England (and Wales) Youth Cohort Study, changes in both absolute and relative social class differences within and across the two countries were analysed through the use of a series of ordered logits. The results show that Scotland has higher educational attainment rates but also higher social class inequalities than England. Moreover, while in England social class inequalities at upper-secondary and tertiary level have declined over time, in Scotland no evidence of such trend has been found. The conclusions highlight that possible explanations for these patterns reside in the different features of the two education systems and in the remarkable educational success of the Scottish middle class.
